Technical Field
[0001] This utility model relates to the field of mechanical equipment manufacturing technology, specifically to a novel double-headed edge banding strip winding device. Background Technology
[0002] Edge banding is currently widely used in furniture board products. Its main functions are to protect the cross-section of the board, inhibit formaldehyde release, improve aesthetics, and enhance safety protection. It is an indispensable functional material in modern furniture manufacturing. In the actual production process, edge banding usually needs to be rolled up after manufacturing, printing, drying and other processes to facilitate packaging, storage and transportation.
[0003] The original edge banding strip winding device has certain structural design flaws. The main flaw is that the edge banding strip winding disc is movably embedded in a specially opened through hole on the rotating worktable, and the edge banding strip winding disc is positioned and installed on the rotating worktable by a separate limiting component. This allows the disc drive device to wind the edge banding strip winding disc together with the rotating worktable when driving the disc to rotate. At the same time, a cylinder and a pneumatic gripper are separately installed under the rotating worktable. The cylinder drives the pneumatic gripper to clamp the edge banding strip on the circumference of the edge banding strip winding disc to complete the clamping. After the edge banding strip is wound, the pneumatic gripper is removed by the cylinder. However, because the through holes on the rotary table for mounting the edge banding rewinding disc are specially designed, if it is necessary to rewind edge banding of other sizes or types on the edge banding rewinding device, the rotary table and edge banding rewinding disc must be removed together, and then a new rotary table and edge banding rewinding disc suitable for the corresponding size or type of edge banding must be designed and installed. Obviously, this method is not advisable in actual production. Not only is the disassembly and assembly of each component cumbersome, but the cost of replacing or redesigning components is also very high, which seriously affects the edge banding rewinding efficiency. Furthermore, the edge banding clamping structure in the original edge banding rewinding device is also relatively complex, with multiple auxiliary structures or components to cooperate in clamping, which is inconvenient to disassemble and assemble and increases the overall manufacturing cost of the device. Moreover, since the edge banding rewinding disc is embedded in the rotary table, the size of the rotary table is relatively large, which in turn increases the size of the entire edge banding rewinding device, resulting in low space utilization. Therefore, the original edge banding rewinding device has great limitations in its structural design. Not only is it inconvenient to operate, but its structure is also complex and not compact enough, resulting in high manufacturing costs. Furthermore, it is inconvenient to disassemble and maintain, which seriously affects the edge banding rewinding efficiency. Its function is also relatively simple, as it can only rewind a single edge banding product and cannot meet the current demand for rewinding multiple types of edge banding products.
[0004] In conclusion, it is necessary to further improve the existing structure. Summary of the Invention
[0005] To address the problems existing in the aforementioned background technology, this invention proposes a structure with a simple and reasonable design, compact arrangement of structural components with high space utilization, low manufacturing cost, convenient operation and use, and easy assembly and disassembly.

[0018] By adopting the above technical solution, this utility model has the following beneficial effects:
[0019] This utility model relates to a novel double-headed edge banding strip winding device with a simple and reasonable structural design, compact overall layout, high space utilization, low manufacturing cost, and convenient operation and disassembly. Specifically, the winding chuck is arranged in a top-mounted configuration, positioning it in the center of the top surface of the rotating worktable during winding. Compared to the original embedding method, this significantly improves the space utilization of the rotating worktable. Furthermore, two winding chucks of different models or sizes can be installed simultaneously on one device, and the disassembly and assembly of each chuck are extremely convenient. When changing the type of edge banding strip during winding, simply use a transverse bidirectional cylinder to drive one of the corresponding winding chucks laterally to the designated position above the rotating worktable, while the other winding chuck is simultaneously moved away from the rotating worktable by the transverse bidirectional cylinder, avoiding… This design eliminates interference during the winding process and enables rapid and precise adjustment of the winding of different types of edge banding strips. Without replacing the winding chuck, two types of edge banding strips can be continuously wound alternately within one cycle. Because the winding chuck is easy to install and remove, if it is necessary to wind two different types of edge banding strips or replace one type in the next cycle, only two or one model of winding chuck needs to be removed to allow for continuous alternating winding of the two types of edge banding strips in the next cycle. This structural design significantly reduces the frequency of winding chuck replacement, reducing component wear and personnel fatigue caused by frequent replacements. While ensuring the stability of edge banding strip winding quality, it significantly improves edge banding strip winding efficiency. The high utilization efficiency of a single winding device greatly reduces the production cost of edge banding strips.
[0020] In this invention, except for the winding drive motor used to drive the rotary worktable, the driving devices for other mechanisms are mostly implemented using cylinders. This ensures stable winding while reducing the overall manufacturing cost of the device. Furthermore, this invention features an edge banding clamp on one side of the winding chuck. A cylinder with an expansion block drives the winding wheel of the winding chuck to expand, clamping the edge banding between the winding wheel and the clamp. Compared to the original method of clamping the edge banding using separate clamp drive devices and winding chuck drive devices, this clamping structure is simpler, uses fewer parts, and is less expensive. It is also easier to disassemble and maintain, ensuring stable clamping of the edge banding while further reducing the overall manufacturing cost of the winding device. Therefore, this invention effectively meets the needs of winding various types of edge banding and is suitable for widespread application. Attached Figure Description

The second edge sealing strip pressing plate is arranged opposite to the first edge sealing strip pressing plate and can press the edge sealing strip between the first edge sealing strip pressing plate and the second edge sealing strip pressing plate under the drive of the edge sealing strip clamping cylinder. After the edge sealing strip is pressed between the first edge sealing strip pressing plate and the second edge sealing strip pressing plate, the sliding plate drive cylinder is activated to drive the moving sliding plate 31 to move laterally into place, and then the edge sealing strip traction bidirectional cylinder is activated to pull the edge sealing strip to the outer circumference of the corresponding take-up chuck 5.
[0035] The edge banding strip shearing mechanism 4 is matched and installed on the bottom side of the movable slide plate 31 of the edge banding strip feeding mechanism 3. It includes a pair of scissor lifting drive cylinders 40 installed on the bottom side of the movable slide plate 31, a pair of edge banding strip shearing drive cylinders 41 respectively installed on the power output end of the pair of scissor lifting drive cylinders 40, and edge banding strip scissors 42 matched and installed on the power output end of the pair of edge banding strip shearing drive cylinders 41. The pair of edge banding strip shearing drive cylinders 41 are respectively located below the waste outlet 312 on the feeding side and the discharge side of the movable slide plate 31, and are both connected to the outside through solenoid valves. The air source and electrical control device 4 are connected; the edge banding shears 42, driven by the edge banding shearing drive cylinder 41, move up and down through the waste outlet 312 on the movable slide plate 31; when a roll of edge banding is finished, a pair of shear lifting drive cylinders 40 are activated to extend the pair of edge banding shearing drive cylinders 41 and edge banding shears 42 to the top surface of the lower housing 11, and then the edge banding shearing drive cylinder 41 is activated to drive the edge banding shears 42 to cut off the excess edge banding at the waste outlet 312, and the cut waste flows out from the waste slide 313.
[0036] The edge banding strip dispensing mechanism 5 is matched and disposed on one side of the worktable 113 and located next to the rotary worktable 114. It includes an edge banding strip dispensing bracket 51, an edge banding strip pushing drive cylinder 52, and a pushing rod.

In this embodiment, the edge banding strip pushing cylinder is a rotary cylinder, which rotates and pops out or retracts the pushing rod to realize the pushing action. The push rod is initially located radially outward of the circular rotary worktable 114. After a roll of edge banding strip is wound up, the push rod is extended by opening the edge banding strip push cylinder to push the edge banding strip out of the rotary worktable 114. After the push is completed, the edge banding strip push cylinder drives the push rod back to its original position. Then the edge banding strip discharge bidirectional cylinder is activated to drive the edge banding strip push cylinder and the push rod to retract together to the feeding side of the worktable 113.
[0037] The edge banding rewinding mechanism 6 is mounted on the mounting bracket 121 of the upper casing 12 of the housing 1. It includes a horizontally moving bidirectional cylinder 61, a lifting bidirectional cylinder 62, a lifting mounting bracket 63, and a expanding block drive cylinder 64. The horizontally moving bidirectional cylinder 61 is horizontally arranged and connected to the electronic control device 2 and an external air source via a solenoid valve. Its cylinder body is slidably mounted on the cylinder body sliding support rod of the mounting bracket 121, and the cylinder rods on both sides are fixedly connected to the mounting bracket 121. Two sets of cylinder body sliding support rods are also mounted on the outer wall of the cylinder body of the horizontally moving bidirectional cylinder 61.

The cylinder bodies of the pair of lifting bidirectional cylinders 62 are slidably mounted on the two sets of cylinder body sliding support rods on the outer wall of the cylinder body of the horizontally moving bidirectional cylinder 61 and can rise and fall along the cylinder body sliding support rods. The cylinder rods are all fixedly connected to the outer wall of the cylinder body of the horizontally moving bidirectional cylinder 61. The lifting mounting bracket 63 has a pair and is fixedly installed on the outer wall of the cylinder body of the pair of lifting bidirectional cylinders 62; each lifting mounting bracket 63 can be lifted and lowered under the drive of the lifting bidirectional cylinder 62 and has a shaft tube 631 vertically installed at the lower center through a bearing; the lower end of the shaft tube 631 extends downwards from the lifting mounting bracket 63. The expansion block drive cylinder 64 is a pair, vertically mounted inside the pair of lifting mounting frames 63, and connected to the electronic control device 2 and an external air source respectively via solenoid valves. The cylinder rod of each expansion block drive cylinder 64 is movably inserted into the shaft tube 631, and a spherical groove is formed in the center of the end face. At the same time, symmetrical limiting surfaces are formed on the opposite circumferential surfaces of the cylinder rod of the expansion block drive cylinder 64. A limiting plate 641 is fixed on one side of the expansion block drive cylinder 64. The limiting plate 641 has a vertically penetrating limiting groove and slides with the limiting surfaces on the opposite sides of the cylinder rod of the expansion block drive cylinder 64 through the limiting groove, thereby limiting the rotation of the cylinder rod of the expansion block drive cylinder 64. Each lifting mounting frame 63 is also equipped with a positioning sensor on one side of each expansion block drive cylinder 64. The positioning sensor is electrically connected to the electronic control device 4.
[0038] The winding chuck 7 has a pair of shaft tubes 631 that are detachably matched and installed on the lower end of the lifting mounting frame 63 of the edge banding winding mechanism 6; wherein, each winding chuck 7 includes a mounting shaft 71, a tension block 72, a sliding plate 73, a bearing assembly 74, a spring positioning pin 75, a winding wheel 76, and an edge banding clamp 77.
[0039] The upper end of the mounting shaft 71 is detachably connected to the lower end of the shaft tube 631 of the lifting mounting frame 63 of the edge banding winding mechanism 6. It has an internal accommodating space and an open bottom. A pair of bearing clearance grooves 711 are symmetrically formed on the bottom end of the mounting shaft 71 relative to its two side walls. A clamping plate mounting hole 712 is also formed on one side wall of the mounting shaft 71. A through hole 713 extending axially from the top center of the mounting shaft 71 into its inner cavity is also formed. In this embodiment, the upper end of the mounting shaft 71 and the lower end of the shaft tube 631 of the lifting mounting frame 63 can be detachably connected via a threaded structure or via a connection using mounting holes and fasteners such as screws and bolts.
[0040] The expansion block 72 is matched and installed between the mounting shaft 71 and the slide plate 73. It includes an expansion block body 721 and a connecting rod 722 fixedly installed on the upper part of the expansion block body 721. The lower part of the expansion block body 721 is inverted conical or has a symmetrical inclined structure. The connecting rod 722 is vertically fixed to the top center of the expansion block body 721. Its upper end passes through the inner cavity and through hole 713 of the mounting shaft 71 from bottom to top and extends outward above the mounting shaft 71. The top center of the connecting rod 722 has a spherical protrusion 7221 similar to a steel ball. The top of the connecting rod 722 is in active contact with the spherical groove at the end of the cylinder rod of the expansion block drive cylinder 64 through the spherical protrusion 7221. This ensures that the cylinder rod of the expansion block drive cylinder 64 only applies axial force to the expansion block 72. When the expansion block 72 rotates, the cylinder rod of the expansion block drive cylinder 64 does not rotate with it. This method of the expansion block drive cylinder 64 not rotating with the expansion block 72 ensures the stability, reliability and safety of the expansion block drive cylinder 64, and also saves energy and reduces costs. The expansion block body 721 and the connecting rod 722 adopt a detachable split structure. The advantage of this split structure design is that when either the expansion block body 721 or the connecting rod 722 wears down after prolonged use, causing errors, the worn part can be easily removed and replaced, allowing for continued use with the other. This avoids the resource waste of replacing the entire expansion block 72 when it wears down, as is common in integrated designs, thus saving costs. The expansion block body 71 has a connecting rod insertion hole from the top center inwards, and a set of connecting rod fixing holes extending to the connecting rod insertion hole are located in the middle of opposite sides. The lower end of the connecting rod 722 is inserted into the connecting rod insertion hole and secured to the expansion block body 721 with fasteners through the connecting rod fixing hole. Alternatively, the expansion block body 721 and the connecting rod 722 can also be detachably assembled using a threaded connection.
[0041] The slide plate 73 is fitted to the bottom of the mounting shaft 71. A cross-shaped groove 731 is formed by the intersection of horizontal and vertical lines in the center of the slide plate 731. A pair of spring pin positioning holes 7311 are symmetrically provided on the outer sides of the horizontal slots of the cross-shaped groove 731. A pair of mounting holes 7312 are symmetrically provided on the opposite sides of each spring pin positioning hole 7311. The slide plate 7312 is fitted to the bottom of the mounting shaft 71 with fasteners through the mounting holes 7312.

In this embodiment, the take-up reel 76 is composed of two separate semi-circular take-up blocks 761. The two semi-circular take-up blocks 761 are respectively matched and fixedly installed on the bottom of the take-up reel mounting plates 741 of a pair of bearing assemblies 74 and are connected to each other by a return spring. Specifically, the two semi-circular take-up blocks 761 are assembled and fixed to the bottom of the take-up reel mounting plate 741 through the take-up reel mounting holes 7412 on the take-up reel mounting plates 741 of the pair of bearing assemblies 74 with fasteners.

[0047] Meanwhile, position sensors for real-time detection of the lifting and lateral movement of the winding chuck 7, and position sensors for pushing the edge sealing strip are also arranged around the rotary worktable 114.

[0048] The electrical control device 2 includes a PLC controller, a motor drive module, and an operation panel. The motor drive module is located inside the lower casing 11 of the housing 1, with one end electrically connected to the PLC controller via a signal line, and the other end electrically connected to the winding drive motor and the solenoid valves of the aforementioned cylinders via signal lines. The PLC controller is installed inside the lower casing 11 of the housing 1, and is electrically connected to the solenoid valves of the aforementioned cylinders, as well as the positioning sensor and various position sensors via signal lines. The operation panel is located on one side of the housing 1 and is electrically connected to the PLC controller via signal lines.
[0049] The working principle of this utility model is as follows:
[0050] First, the two take-up chucks 7 corresponding to the edge banding strip to be wound in one cycle are respectively installed at the lower ends of the shaft tubes 631 of the two lifting mounting frames 63. Then, the take-up chuck 7 used for priority winding is determined, and the transverse bidirectional cylinder 61 is started by the electronic control device 2, which brings the lifting bidirectional cylinder 62, the lifting mounting frame 63, and the expansion block drive cylinder 64 corresponding to the take-up chuck 7 used for priority winding to the top of the rotary table 114. At the same time, the positioning sensor installed on the lifting mounting frame 63 detects the position of the positioning hole on the rotary table 114 in real time and transmits the positioning signal to the electronic control device 2. The electronic control device 2 controls the take-up drive motor to start in real time according to the received positioning signal, so as to drive the rotary table 114 to rotate and dynamically find the positioning hole. After that, the rotary table 114 stops rotating. Then, the electronic control device 2 controls the lifting bidirectional cylinder 62 to start, so as to drive the lifting mounting frame. 63. The expansion block drive cylinder 64 and the take-up chuck 7 descend together, quickly and accurately inserting the spring positioning pin 75 on the take-up chuck 7 into the positioning hole in the center of the rotary table 114, thus achieving the positioning and installation of the take-up chuck 7 and the rotary table 114. At this time, the electronic control device 2 controls the start of the slide plate drive cylinder of the edge banding feeding mechanism 3 to drive the moving slide plate 31 to move laterally into place. The electronic control device 2 controls the start of the edge banding traction cylinder 35 to quickly pull the edge banding clamp between the outer circumference of the take-up wheel 76 of the take-up chuck 7 and the edge banding clamp 77. Then, the electronic control device 2 controls the start of the expansion block drive cylinder 64 to push the expansion block 72 down to expand the take-up wheel 76 and complete the edge banding clamping. Then, the electronic control device 2 controls the edge banding traction cylinder 35 to return to the initial position. Then, the electronic control device 2 controls the start of the take-up drive motor to drive the rotary table 114 to rotate synchronously with the take-up chuck 7 to take up the edge banding. After one roll of edge banding is wound up, the edge banding shearing mechanism 4, controlled by the electronic control device 2, cuts off the excess edge banding. Then, the expansion block drive cylinder 64 is controlled to move upwards to remove the external force on the expansion block 72. At this time, the winding wheel 76, under the action of the return spring, gathers and releases the edge banding. The lifting bidirectional cylinder 62, controlled by the electronic control device 2, is activated to bring the winding chuck 7 back to its initial position and completely detach it from the edge banding roll. Finally, the edge banding discharge mechanism 5, controlled by the electronic control device 2, pushes the wound edge banding roll out of the rotary table, thus completing one edge banding winding operation. Within a cycle, if it is necessary to change to winding a different type of edge banding, simply control the transverse bidirectional cylinder 61, controlled by the electronic control device 2, to move the winding chuck 7 used for winding the corresponding type of edge banding to directly above the rotary table 114, and operate according to the previous winding process.
